Abstract (en)

[origin: EP3605848A1] A polar code encoding method and apparatus are provided, to improve accuracy of reliability sorting of polar channels. The method is: determining a sorted sequence used to encode to-be-encoded bits, where the sorted sequence is used to represent reliability sorting of N polar channels, N is a mother code length of a polar code, and N is a positive integer power of 2; and performing polar code encoding on the to-be-encoded bits by using the sorted sequence, to obtain encoded bits.
